How to Prevent Water Intrusion on Sliding Glass Doors

What Are the Reasons for Water Intrusion on Sliding Glass Doors?

1. Poorly-Sealed Doors

If your sliding glass door is not properly sealed, water can easily enter through gaps and cracks. Make sure to check the seals around your door regularly and replace them if necessary.

2. Poor Drainage

If water cannot drain properly away from your door, it can pool around the base of the door and eventually make its way inside. Make sure that there is proper drainage around your door and that any gutters or downspouts are clear of debris.

3. Improper Installation

If your sliding glass door was not installed correctly, it might not be level with the ground outside. This can allow water to seep underneath the door and into your home. Make sure that your door is installed level with the ground and that there is a proper slope away from the door to allow water to drain.

4. High Winds

If you live in an area with high winds, your sliding glass door can be blown open, even if it is locked. This can allow water and debris to enter your home. Make sure that your door is securely locked and that nothing is blocking it from opening.

If the glass in your sliding glass door is damaged, it may be more susceptible to water intrusion. Make sure to inspect the glass regularly and replace it if necessary.

Why It’s Important to Prevent Water Intrusion on Sliding Glass Doors?

Anyone who has ever dealt with a leaky window knows the importance of preventing water intrusion. Water can cause all sorts of problems, from mold and mildew to wood rot and structural damage. And when it comes to preventing water intrusion, sliding glass doors are particularly vulnerable.

That’s because they’re often located on the ground floor, where they’re subject to all kinds of precipitation, from rain and snow to sprinkler overspray. In addition, sliding glass doors are often left open for extended periods, leading to water damage.

Fortunately, you can take a few simple steps to prevent water intrusion on your sliding glass doors.

8 Ways to Follow on How to Prevent Water Intrusion on Sliding Glass Doors

1. Inspect and Repair Seals Regularly

The first step in preventing water intrusion on sliding glass doors is to make sure that the seals are in good condition. Inspect the weatherstripping and seals around the door regularly for any cracks or gaps. If you find any damage, repair it immediately with caulk or another sealant.

2. Keep the Track Clean

Another way to prevent water intrusion is to keep the track clean. Over time, the track can become clogged with dirt and debris, which can cause the door to not seal properly. To clean the track, first, remove any debris with a brush or vacuum. Then, wipe down the track with a damp cloth.

3. Inspect the Door

If you find that water is still getting into your home, despite taking these precautions, it may be time to replace the door. Sliding glass doors are only as good as the frame they’re in. If the frame is damaged, it will allow water to seep in, no matter how well the door is sealed. Inspect the frame for any cracks or gaps. If you find any damage, it’s best to replace the door entirely.

4. Check the Weatherstripping

The weatherstripping around your door plays a crucial role in keeping water out. Inspect it regularly to ensure it is in good condition and properly sealing the door. If the weatherstripping is worn or damaged, replace it immediately.

5. Install a Door Sweep

A door sweep is a strip of material that fits on the bottom of your door to create a seal. It helps to prevent water from seeping in through the cracks and crevices around your door. Door sweeps are relatively easy to install and can be found at most hardware stores.

6. Use Caulking

Caulking is another great way to seal up any cracks or gaps around your door. Simply apply a bead of caulk around the perimeter of your door and smooth it out with your finger. Caulking is an inexpensive and easy way to prevent water intrusion.

7. Apply a Waterproofing Membrane

If you live in an area with high rainfall or severe weather, you may consider applying a waterproofing membrane to your door. Waterproofing membranes are applied like paint and create an invisible barrier that prevents water from seeping through.

8. Add a Threshold

Thresholds are an important part of any door, but they’re especially important for sliding glass doors. A threshold will help to keep water and debris from entering your home. There are a variety of thresholds available, so be sure to choose one that fits your needs.

Now that you know how to prevent water intrusion on sliding glass doors take the necessary precautions to keep your home safe and dry. Follow the tips above to ensure your door is properly sealed and protected from the elements.

How Do You Caulk the Bottom of A Sliding Glass Door?

Have a drafty sliding glass door? You caulk the bottom of a sliding glass door just like any other door – by caulking the space between the door and the frame.

Use a putty knife or finger to smooth out the caulk, then remove any excess with a damp rag. That’s it! In just a few easy steps, you can seal up that drafty sliding glass door and keep your home warm and cozy all winter long.
